Geothermal heating floor is also called low-temperature hot water radiant heating floor. Low-temperature floor radiation is a system that utilizes the ground inside the building for heating. It is the entire floor as a radiator laying in the floor structure of the pipeline, through the pipeline into the low temperature of 60 °C below the heating floor concrete layer to maintain the ground temperature around 26 °C, make people feel warm and comfortable. The indoor temperature dropped evenly, giving people the best feeling of cooling their heads and heads, consistent with human physiological sciences.
It saves the effective use of the room and saves energy. The actual temperature of the low-temperature hot water floor heating is 2°C to 4°C higher than the actual temperature. It complies with the requirements of “measured by household and temperature in separate roomsâ€. When no one is in the house, heating can be stopped. When the population is small, heating can be performed in rooms where people are active and the valves of unoccupied rooms can be closed.
With long service life, the aluminum-plastic composite pipe used is a world-acclaimed material with a service life of 50 years. In addition, this heating method also has the characteristics of reducing floor noise, cleaning and hygiene, wide selection of heat sources, and adaptation to old houses.
Measuring a real geothermal floor requires many specific technical parameters. First of all, it must have good heat dissipation. Geothermal flooring is very particular about the choice of materials, and strictly selects those special substrates whose wood density meets the requirements. The floor thickness is between 6.5-8.5 mm (the standard thickness of the floor heating floor) to ensure that the floor has good air permeability and heat dissipation. The second characteristic is heat resistance. The finished product of the geothermal floor has actually had a little bit of taste. Four cycles of rigorous testing must be performed during the manufacturing process. That is, the floor is cooked in hot water at 100°C for 4 hours → baked in an oven at 60°C for 20 hours → cooked in hot water at 100°C for 3 hours → frozen at minus 20°C for 2 hours. Round-trip four times to ensure long-term high-temperature floor, no cracking, no degumming, anti-moisture, no deformation, no warping. The last point is green. Health and safety are fundamental requirements of geothermal flooring. Products should comply with international environmental protection standards (E1 European environmental protection standards; Japan's environmental protection standards for F1; China's formaldehyde release content of less than 0.12mg/m3 equivalent to international standards).
Because specialized geothermal floor prices are relatively expensive, the average wage earners hope to find a cheap and affordable product that is affordable and meets the requirements. Here are several alternatives to introduce to you. There are several types of wood flooring suitable for underfloor heating systems. First, laminate flooring of 7 to 8 mm thick, with 2 to 3 mm foam cushions; and second, 3 or more layers of 8 to 12 mm thick Parquet, with 2 to 3 mm foam cushions; 3rd, 8 mm thick spliced ​​parquet or mosaic floors, 2 to 3 mm foam cushions; 4th, 10 to 12 mm thick The solid wood flat floor; fifth, the wooden floor with the length, width and height of less than 600 × 60 × 15 mm respectively, the best is the floor of 200 × 40 × 10 mm size, which is spelled into a square or herringbone during construction. Make it heat-distributed evenly.
In short, the selection of geothermally heated wood floors requires the following principles: the size of the wooden floor should be stable, the heat stability should be better, the moisture content should be lower, so that the floor will not be easily deformed after being heated; it is beneficial to heat exchange and conduction, and the cushion material should not be suitable. Too thick; floor size should not be thin and thick, should not be narrow width, in order to facilitate the anti-deformation, heat conduction requirements.
The advantages and disadvantages of solid wood flooring and composite flooring
Solid wood flooring is the ground decoration material that has been dried and processed. It has a natural pattern, comfortable foot feeling and safe use. It is an ideal material for the floor decoration of bedrooms, living rooms, and study rooms. The decorative style of solid wood is back to nature, and the texture is natural. In the case of a decline in the forest coverage rate, today's environmental protection is strongly promoted. Solid wood flooring is even more precious. Solid wood flooring is divided into three grades: AA grade, A grade, and B grade, and AA grade has the highest quality.
In the purchase of solid wood flooring should pay attention to the detection of wood moisture content, high moisture content of the floor, must be deformed after installation. In the north of China, the floor moisture content is 12%, and the floor moisture content in the southern region should also be controlled within 14%.
Composite flooring is a popular flooring material in recent years. After the wood is crushed, it is filled with glue, preservatives, and additives, and then processed by high-temperature and high-pressure pressing of the hot press. Therefore, it breaks the physical structure of the logs and overcomes the weakness of the poor stability of the logs. Composite flooring has high strength, uniform specifications, high wear-resistance coefficient, anti-corrosion, anti-mite and good decorative effect. It overcomes the problems of knots, wormholes and chromatic aberrations on the surface of logs.
Composite flooring does not need to be painted and waxed. It is widely used and easy to care for. It is the most suitable floor material for the rhythm of modern family life. In addition, the composite floor has a high wood usage rate and is a very good environmental protection material. How to choose a good floor for home use:
Select the floor according to your actual situation, the following will introduce you to some knowledge about the floor.
First, the classification of composite flooring Compound flooring currently on the market there are two main categories: one is solid wood composite flooring; the other is reinforced laminate flooring. These two types of laminate floorings have different characteristics and require different requirements for use and maintenance.
Solid wood composite flooring has both natural and comfortable flooring, comfortable footwork, and good insulation properties. It also overcomes the insufficiency of solid wood flooring due to the shrinkage of monomers. Now that the living environment is no longer deteriorating, countries all over the world attach great importance to the protection of forest resources. Solid wood flooring can save precious wood resources compared to solid wood flooring. In addition, solid wood flooring is easy to install, and it is not necessary to use keels in general. However, it requires ground leveling.
Solid wood composite floor can be divided into three categories of solid wood composite floor, multi-layer solid wood composite floor, fine wood composite floor three categories, more than three layers of solid wood composite floor in the room decoration.
The three-layer structure solid wood composite floor is formed by three layers of solid wood, and the surface is made of high-quality hardwood specifications. The commonly used tree species are ash, birch, beech, beech, maple, and cherry. The middle is a cork board, and the bottom layer is a rotary board, arranged in a crisscross pattern. This structural composition makes the three-layer solid wood composite floor not only has the advantages of ordinary solid wood flooring, but also effectively adjusts the internal stress between the wood, and improves the shortcomings of the wood with large changes in dry humidity during the season.
The solid wood floor has a good foot feeling, natural texture and color, and slightly less hardness. And because it is natural, textures and colors vary greatly. Wooden keels are required when paving, and the price is relatively high.
The high-strength composite flooring has high hardness, good wear resistance, simple and convenient pavement, and low price, but the foot feels slightly worse.
Solid wood flooring absorbs the advantages of the above two, the price is between the two, but the hardness is the worst of the three.
Second, how to choose when selecting composite flooring, we must ensure that the main indicators qualified. These indicators and national standards are:
1. Thickness of water-absorbing thickness: The water-absorption thickness expansion rate of excellent products is below 2.5%; the water-absorption thickness expansion rate of first-class products is below 4.5%. With water bubbles, the quality of water absorption is poor.
2, the surface wear resistance: the floor because there is no wear layer or abrasion resistance is extremely low and is called false floor, this floor surface and real composite floor no difference with sandpaper after grinding several times, will find The decorative pattern was polished and whited immediately. This floor is a fake floor.
The service life in public places will generally not exceed six months.
The stronger the grinding, the price is also more expensive. The number of wearable revolutions in public places is above 9000 rpm; if you have a large population in your home, you don’t pay much attention to maintenance, you can choose some higher wear resistance; but if you pay more attention to the maintenance of the floor, the floor is subject to strong and hardware wear. With fewer opportunities, it may be more economical to choose a bit lower wear resistance. Family wear-resistant rotations can be more than 6,000 rpm. . Can be rubbed with sandpaper, poor quality is easy to find. The wear resistance of composite flooring mainly depends on the coating of aluminum oxide crystals (commonly known as gemstones). The higher the aluminum oxide crystal content per unit area of ​​the floor, the higher the degree of wear resistance.
3, formaldehyde emission: A grade of formaldehyde release value of 9mg/100g or less. B pole 9 to 40 mg / 100 g, to reach the B level can be used. The quality of the glue determines the degree of contamination of the laminate flooring, and the quality of the good glue formaldehyde is low.
Ou Dian's floor formaldehyde content is only 5MG/100G, which is lower than the EU standard and ranks first. It has become the first imported green product certified by the China Environmental Labeling Committee.
4, density: the density of qualified products ≥ 0.9g/cm3.
5. Moisture content: The moisture content of the qualified products is in the range of 3.0-10.0%. When people purchase floors, they can check the data through product inspection certificates.
6. Check whether the business outlet is straight. The completeness of the mouth is directly related to the life of the floor.
7, the surface of the impregnated plastic film paper veneer should not have dried flower opaque white dots, wet flower spray, stains, scratches and indentation, around the tongue and tongue and groove should remain intact. The length, width, and thickness of the composite plate should be the same as those of the product introduction. You can take as many pieces of composite flooring as you like to observe after combining them. See if the splicing seams of boring heads are uneven or not. Assemble by yourself to observe whether the jaws and grooves are tightly combined and feel smooth. The middle layer of parquet can not only increase the feeling of foot, but also prevent the expansion and deformation of the floor. The thickness should be 7-10mm. In the material selection, the quality of rubber wood and pine wood in the middle layer is higher, followed by willow wood. Multi-layer solid wood composite floor often uses multi-layer plywood as the base material, and the surface decoration panel is mostly made of hardwood laminations, and the thickness is usually between 0.2-0.8 mm.
8, the middle layer of solid wood flooring, not only can increase the sense of foot, but also to prevent the expansion of the floor deformation, the thickness of 7-10mm is appropriate. In the material selection, the quality of rubber wood and pine wood in the middle layer is higher, followed by willow wood. Multi-layer solid wood composite floor often uses multi-layer plywood as the base material, and the surface decoration panel is mostly made of hardwood laminations, and the thickness is usually between 0.2-0.8 mm.
Consider the size of the living area. Under normal circumstances, if the room is large and the lighting is sufficient, a darker, thicker texture wood floor should be selected to make the relatively large room relatively compact. On the other hand, the room with a small area can use light colors and textures. The wooden floor gives a sense of openness and will make the smaller room appear spacious.
9, consider the different functions of each room, different rooms can choose to use different colors of wood flooring. The living room is the most open place in the family, and it is also the main place for family members to conduct daily activities and receive guests. Therefore, it is advisable to use high transparency and soft colors to create a clear, harmonious and elegant atmosphere; the bedroom is for rest and relaxation. Place, should use warm colors or some neutral colors of the floor, giving a quiet, comfortable feeling; Children's room is the place for children to sleep, study, and living, should be simple, cheerful, clear, using light and bright colors will be good; The study room is the place where the house owner works and studies, and the environment should have a strong cultural atmosphere.

Sodium phosphate is a generic term for a variety of salts of sodium (Na+) and phosphate (PO43−).
Sodium phosphates have many applications in food and for water treatment. For example, sodium phosphates are often used as emulsifiers (such as in processed cheese),thickening agents, and leavening agents for baked goods. They are also used to control pH of processed foods. They are also used in medicine for constipation and to prepare the bowel for medical procedures. Moreover, they are used in detergents for softening water, and as an efficient anti rust solution.
